changed username on git, can't authenticate

[SmatchyLaPaglia]

Is there a way to get my GitHub repository to reconnect with my local git after I've changed my username?

You can adjust the remotes here:

currently edit is not supported so you would have to remove the old one and then add the new one.

On the commandline it is possible to edit them: https://docs.github.com/github/getting-started-with-github/getting-started-with-git/managing-remote-repositories

There is no UI for this kind of config changes right now and hopefully one day we can.

But honestly, these kind of changes are rare and not sure if we get much mileage by putting UI for this.
